- Q1Which of the following is a true statement?Terrestrial ecosystems are found on land, while aquatic ecosystems are found under waterAquatic ecosystems are found on land, while terrestrial ecosystems are found under waterAquatic ecosystems have warmer temperatures in the summerTerrestrial and aquatic ecosystems share the same organisms60sHS-ESS3-1
- Q2Which of the following is NOT a main body of water?DamOceanSeaRiver60sHS-ESS3-1
- Q3What is the difference between marine and freshwater ecosystems?pHTemperaturedepthsalinity60sHS-ESS3-1
- Q4Why is an estuary considered a transitional community?They can change temperature with the seasonsEstuaries are the areas where fresh water and salt water ecosystems meet.Estuaries are the areas where the sea and ocean meet.They can change the type of organisms that live in them by changing their amount of oxygen60sHS-ESS3-1
- Q5What is the difference between the photic and aphotic zone?The aphotic zone is where there is no light and there are more living organismsThe photic zone is the region of a marine ecosystem from 200m and deeper.The aphotic zone is the upper region of a marine ecosystem where light can penetrate.The photic zone is the upper region of a marine ecosystem where light can penetrate.60sHS-ESS3-1
- Q6Which of the following is one of the four factors that affect aquatic ecosystems?amount of sugaramount of oxygenamount of lightpH60sHS-ESS3-1
- Q7Which of the following statements is INCORRECT?there is less dissolved oxygen the deeper you go in the oceanthe photic zone would be warmer because it is exposed to sunlightThe aphotic zone has a warmer temperature because it is exposed to sunlightthere is less life at the bottom of the ocean floor60sHS-ESS3-1
- Q8Which of the following correctly explains the graph?the temperature constantly decreases from summer to springthere is more dissolved oxygen in summerAs the temperature decreases, the dissolved oxygen concentration increases in summer and autumnthe temperature is directly related to the dissolved oxygen60sHS-ESS3-1
- Q9Why aren't there plants on the ocean floor?There are plants on the ocean floor.Plants cannot survive without oxygenThere is less available oxygen at the bottom of the ocean floor because less animals are down therePlants need sunlight to survive and go through photosynthesis. There is no sunlight on the ocean floor.60sHS-ESS3-1
- Q10Which of the following correctly explains the graph?the dissolved oxygen is the independent variableThe temperature is the independent variablethe seasons (summer, winter, spring, and autumn) are the dependent variablesThe temperature and the dissolved oxygen are the dependent variables60sHS-ESS3-1
